go-chi-jsonapi

go-chi-jsonapi is a collection of utilities to facilitate the implementation of JSON:API HTTP APIs with go-chi

render package

The render package provides a JSON API responder and decoder that can be easily integrated into go-chi/render. It provides DefaultResponder and DefaultDecoder functions to be set in go-chi/render

To make integration simpler it re-implements some of the go-chi/render functions and delegates to the orginal one, the implementation is heavily inspired by go-chi/render.

This package uses google/jsonapi. Structs must have proper jsonapi tags, see jsonapi Tag Reference. Payload must be given as a struct pointer or a slice of struct pointers, this is how google/jsonapi works.

Supported features:

• DefaultResponder and DefaultDecoder functions for easy integration with go-chi/render
• Detects Content-Type from request Header and decodes accordingly (can be overriden using render.SetConentType middleware)
• Detects Accept type from request Header and encodes accordingly (can be overriden using render.SetConentType middleware)
• Automatically encodes errors as JSON API Error Objects (when Accept is set to JSON API)
• Can be used by calling render.Respond/render.Decode or render.Render/render.Bind

Examples

Renderer

Using render.Respond and render.Decode

    import (
        jsonapi_render "github.com/fjgal/go-chi-jsonapi/render"
        "github.com/go-chi/render"
    )

	// plug jsonapi responder and decoder
	render.Respond = jsonapi_render.DefaultResponder
	render.Decode = jsonapi_render.DefaultDecoder

    // implement a handler function
    router.Get("/", func(w http.ResponseWriter, r *http.Request) {
        var blog Blog
        // decode the request body into a struct
        _ := render.Decode(r, &blog)
        // set response status
        render.Status(r, http.StatusAccepted)
        // render the response
        render.Respond(w, r, &blog)
    })

Responding with an error

    import (
        jsonapi_render "github.com/fjgal/go-chi-jsonapi/render"
        "github.com/go-chi/render"
    )

	// plug jsonapi responder and decoder
	render.Respond = jsonapi_render.DefaultResponder
	render.Decode = jsonapi_render.DefaultDecoder

    // implement a handler function
    router.Get("/", func(w http.ResponseWriter, r *http.Request) {
        render.Status(r, http.StatusUnprocessableEntity)
        render.Respond(w, r, err)
    })

Using render.Render and render.Bind (model structs must implement render.Renderer and renderBinder interfaces)

    import (
        jsonapi_render "github.com/fjgal/go-chi-jsonapi/render"
        "github.com/go-chi/render"
    )

    router.Get("/", func(w http.ResponseWriter, r *http.Request) {
        var blog Blog
        _ := render.Bind(r, &blog)
        render.Status(r, http.StatusAccepted)
        err = render.Render(w, r, &blog)
        if err != nil {
            t.Log(err)
            return
        }
    })

TODO

• [] implement queryparams package
• [] support json api streaming ?
